How to dynamically get a property by name from a C# ExpandoObject?

Question

I have an ExpandoObject and want to make a getter for it that will return a property by name at runtime, where the name is specified in a string instead of hard

Answer 1

ExpandoObject provides access both via dynamic and via IDictionary<string,object> - so you could just use the dictionary API:

var byName = (IDictionary<string,object>)account.features;
bool val = (bool)byName["isEmailEnabled"];

Or if the name is fixed, just:

bool val = ((dynamic)account).features.isEmailEnabled;
